TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, WILLIAM H. IIORTOAT, of Chelsea, in the county ofSuffolk, and State of Massachusetts,

have made a new and' useful invention having reference to Lamp-Shades;and I do hereby declare the same to be fully described in the followingspecification, and represented in the accompanying drawings, of which-Figure l denotes a top view, V

Figure 2 a bottom view, and

Figure 3 a transverse section of a lmnpshade provided with my invention,by which it may be applied to a glass chimney of a common kerosene-lamp.

Figure 4 is a top view, and 4 v Figure 5 a transverse section of a.lamp-shade with my invention, as formed for application of the shade toa gas-burner.

In the drawings, A denotes` the shade, it being a piece of sheet metalbent lin the form analogous to 4the outer Vcurved surface nf the hoof ofa horse. A bar, B, hinged at one end to the inner surface of the shade,slides on an arch-piece or curved arm, C, extended from the saidsurface, and through a slot in the bar. The

purpose of the curved arm is to steady the bar, and ,hold it in anydesirable 'angular position, with the shade within the limits of motionofthe bar on the arm. The arm so holds the bar 4by bearing closely orwith friction against the opposite sides of the slot in'the bar. The barB, at its free end, is jointed to another bar,` D, which terminateseither in a hook', as shown ata, in fig. 3, orvin an eye, as shown at b,in figs. 4 and 5. There also extends from the bar VD a i'ork, E, thesaine being as represented in figs. 1, 2, and 3, orin figs. 4 and 5. Thehook and the fork enable the shadeholder to be applied to a glass-lampchimney, the hook being caught on the top of the chimney, and the forkbeing made to embrace the chimney. The eye is to receive and fit on agasburner, which the fork is to embrace, and thereby aid in holding thepart D to the burner.

By such means, the shade may not only be fixed to butadjusted intodifferent angles with the burner or lamp, as the case may be, and asoccasion may require.

I claim the lamp-shnde supporter and adjuster, consisting of thefriction-arm C, the bars B and D, arranged .nd applied together andtovthoshade as set forth.

I also claim the combination and arrangement of the fork E with the armsC B D, arranged and applied together,and to the shade A, substanliallyas hereinbefore explained.
